Mobile App Development is the creation and development of phones, tablets, personal digital assistants, and other devices that have operating systems. It involves creating software applications for the devices, such as games, utilities, and sometimes even simple to-do lists. These applications are created using programming languages such as HTML5 and JavaScript, which allow developers to create a good user interface. Mobile App Development requires both specific and hard skills from developers, from debugging existing applications to creating entirely new ones.

I want a cross-platform mobile app that serves fresh, uplifting affirmations every day on both iPhone and Android. The content will span three key themes—positive, health, and motivational messages—so users can decide which tone suits them each morning. Core features need to feel effortless: a gentle daily notification, a simple way for people to track what they’ve read or favorited, and a settings area where they can truly make the experience their own. Customization is central to the concept. Users must be able to pick from our preset categories, type in personal affirmations, and switch backgrounds or color themes to match their mood.

I’m building a dedicated Android application for my eyewear chain and I need a developer who can take it from concept to a polished, Play-Store–ready release. The app must recognise that we operate several branches. Each location needs its own working hours, contact details, Google Maps pin, and real-time stock availability. When a customer opens the app, they can immediately see which branch is open, what products are in stock there, and book their appointment accordingly. Our product catalog is the heart of the experience. Frames, lenses, sunglasses and contact lenses should be displayed with photos, prices and “available in store” status. Shoppers must be able to filter by type, price range and availability, not just keyword search. Speed here is critical&mdash...
I want to bring a dedicated Android e-commerce application from concept to Google Play. The core of the build is straightforward: customers must be able to browse products, add items to a cart, and check out smoothly—but the standout requirement is a robust push-notification system that keeps shoppers updated on promotions, order status, and cart reminders in real time. My priority stack is Kotlin with Android Studio, though I am open to proven cross-compatible libraries where it makes sense. Payment processing, user profiles, and basic analytics are already budgeted for the next phase, so please set up the project architecture with future modules in mind. Deliverables: • Production-ready APK plus signed AAB for store release • Complete, well-commented source code in a ...

My AI-generated productivity app is almost ready for prime time. It serves as a lightweight app manager and bundles several utility tools that don’t ship with a stock Android phone. Before it reaches users, I need thorough Functionality, Usability, and Performance testing, followed by hands-on guidance through the entire Google Play release process. Here’s what I need from you: • A clear test plan, execution, and concise report that flags crashes, UI hiccups, slowdowns, or Play-Store-policy risks. • Practical advice—build signing, Play Console setup, screenshots, listing text, content rating, privacy policy links—right up to a successful rollout. • A short knowledge-transfer session so I can repeat the process for future updates. If you’...
I want to create a mobile application inspired by Rapido that lets users book taxis instantly. The flow should feel like a friction-free service-booking platform: pick-up and drop-off locations, see nearby drivers, confirm the ride, then track the car live until arrival. To keep things clear, here is what I expect to be included: • Real-time tracking so riders can follow the driver’s route from acceptance to drop-off. • A driver ratings & reviews system that lets passengers leave feedback and see an average score before they confirm. • Multiple payment options—card, wallet, and cash on arrival at minimum—handled through a secure gateway. iOS and Android releases are both in scope. I will supply brand assets; you will handle UI/UX, backend, driv...
I need a full-featured e-commerce solution deployed on both iOS and Android. The core customer app must showcase rich product listings, let shoppers pay through an integrated gateway, and invite them to leave authentic reviews after purchase. Alongside the customer-facing app, I also require: a lightweight driver/delivery app so couriers can receive orders, update statuses in real time, and navigate to addresses; plus a secure admin panel where I can manage inventory, prices, users, promotions, and review analytics. To keep everything maintainable, please use a modern cross-platform stack (Flutter, React Native, or a solid native duo of Swift and Kotlin—your call, just explain your choice) connected to a scalable backend with REST or GraphQL APIs. Push notifications, basic orde...

If satisfied with work, will provide more projects in app development.
I’m ready to launch an e-commerce experience on Android and need a complete application built from the ground up. The core idea is simple: shoppers must be able to browse a catalog, add items to a cart, pay securely, and track their orders—all within a clean, responsive interface that feels fully native to Android. You’ll focus on coding and UX while I supply the product data, brand colors, and any graphics you need. Material Design principles are a must so the layout adapts gracefully across phones and tablets. Please integrate a widely-used Indonesian-friendly payment gateway such as Midtrans (or propose an alternative) and set up push notifications for order status updates.

Detailed User & Admin Flow Overview User Onboarding & Profile Creation Users begin by accessing the official website (1 page website need to be created by you), which redirects them to download the mobile app (Android / iOS). After installation, users log in using their mobile number via OTP authentication with auto-read and auto-fill for secure, password-free access. Users then complete a structured biodata form including personal details (name, gender – groom/bride, age, height, education, occupation, city, contact details, and family details). Based on this, the system automatically generates a biodata profile with a unique Biodata ID. Users upload 2–4 photos, after which the system automatically generates a watermark (Community Name + Biodata ID) and links it se...

A real-time inventory management dashboard with role-based auth, data visualization, and PDF reporting. The AI Workflow: Architecture: Used Claude 3.5 Sonnet to design the Supabase schema and Row Level Security (RLS) policies to ensure data isolation. Frontend Velocity: Leveraged v0 (Vercel) to generate Shadcn/UI components for the dashboard layout, reducing UI coding time by ~70%. Logic & Integration: Used Cursor (Composer) to wire up React Query mutations and handle optimistic UI updates. Quality Check: AI-generated code was strictly typed (TypeScript) and reviewed. I used GitHub Copilot to generate comprehensive unit tests (Jest) for all critical business logic. Outcome: Shipped a production-ready MVP in 14 days with 95% test coverage on core functions
I’m building a full-featured exam-preparation application in Flutter that must run smoothly on both iOS and Android from day one. The app revolves around a large MCQ question bank, so practice tests with instant explanations, timed mock exams, topic-wise performance dashboards, weak-area analytics, note taking, PDF viewing, and embedded video lessons all need to feel seamless. Only social sign-in is required—Google and Facebook through Firebase Auth or the equivalent flow in Supabase so that piece should be wired up out of the box. Whichever backend you prefer (Firebase or Supabase) must scale effortlessly from an initial ±5 000 users to 50 000 + active learners without re-architecture. A paid subscription tier sits on top of the free core, so Stripe, Razorpay, or a co...
